This is the second of four resource updates on the tailings dumps at Mount Morgan. The first resource update, which was for the No 2 Mill tailings dump, revealed that Indicated Resources there had more than doubled to 100,000oz (ASX: 18 July 2016).

At Mundic Gully, a total of 66 drill holes were completed by Carbine in 2015 and 2016. The drilling was designed to both convert the Inferred Resources to Indicated Resources and to increase the overall resource by testing for potential extensions to the known resource.

At that time, the Mundic Gully tailings dump had a Total Mineral Resource of 1.2Mt at 1.89g/t gold, including 0.8Mt at 1.93g/t gold in the Indicated Resource Category and 0.4Mt at 1.82g/t gold in the Inferred Resource Category (Norton Gold Fields Limited ASX announcement 28 October, 2009).

The new Mineral Resource for Mundic Gully is 1.72Mt at 1.91g/t gold for 105,000 ounces, comprising an Indicated Resource of 1.70Mt at 1.91g/t gold for 104,000 ounces of gold and an Inferred Resource of 0.02Mt at 1.86g/t gold for 1,000 ounces of gold, both reported above a 0.00 g/t gold cut-off grade (Table 1). This new Mineral Resource represents a 100% increase (52,000 ounces) in Indicated Resources and an overall 45% total Mineral Resource increase (32,000 ounces) compared with the previous combined Indicated and Inferred Mineral Resource.

In addition, the Indicated Resource for Mundic Gully contains an estimate of 340,000 tonnes of pyrite, 2,900 tonnes of copper, and 1,500 kilograms of silver.

Lying immediately below the Mundic Gully tailings at its eastern margin, newly defined Red Oxide tailings have also been identified. These western extensions to Red Oxide will be included in the new Red Oxide Resource estimate aimed for completion in early August.

Resource Summary

The Mundic Gully tailings dump was built during the historical mining and processing of the 10 million ounce Mount Morgan primary gold-copper orebody. Oxide tailings were first produced in the early 1900’s and deposited in the lower reaches of Mundic Gully. The majority of tailings were produced as sulphide tailings and deposited over several time periods between 1932 and 1962. Approximately 2.0Mt of these original Mundic Gully tailings were reprocessed from 1986 to 1989 and deposited back into the Mount Morgan open cut.

Sulphide tailings consist dominantly of quartz and pyrite, with minor amounts (<10%) of sericite, chlorite, feldspar, chalcopyrite and sphalerite. Oxide tailings consist of silica, iron oxides and hydroxides. Tailings are deposited as horizontal layers into the pre-existing topography and varies in thickness from 1m to 31.5m (average 12.3m). Up to 40m of waste material overlies the Mundic Gully tailings dump to the west, with most of the gold mineralisation (tailings) starting from an average depth of ten metres.

The Mundic Gully interpretation is based upon 158 drillholes, including 66 Carbine RC and 92 historic RC and aircore drill holes completed by previous owners.

Carbine Resources collected the entire sample from the RC drill rig cyclone (approximately 15 kg) and transferred it to the sample preparation lab where it was dried, crushed to 2mm and subsampled to 3 kg. This 3kg sample was then pulverised to 74 microns and assayed by collecting 50g aliquots for fire-assay of gold (AAS finish), copper, iron, silver and sulphur using ICP-AES. Sample duplicates show excellent repeatability of gold assays (99% correlation). Historic holes have been validated by drilling of twin holes by Carbine Resources.

==> picture [73 x 263] intentionally omitted <==

The detailed topographic surface has been obtained by a 2016 LIDAR airborne survey. The Mundic Gully tailings was constrained by a 3D closed wireframe interpreted from geological logging, adjusted using sulphur and gold grade.

Dry bulk density was measured using the sand replacement method from trenches covering both sulphidic and oxide tailings. A bulk density of 1.76 t/m[3] was calculated for sulphidic tailings and 1.42 t/m[3] for oxide tailings.

==> picture [40 x 40] intentionally omitted <==

Most of the individual samples are 1m in length, with the average of 796 samples being 1.2m. The samples have been composited to 1m in the resource estimate. A high grade top cut of 4.5 g/t gold was applied to composited samples. No top cut was applied to the other elements.

The tailings mineralisation was estimated as a 3D block model for all five elements, Au, Ag, Cu, Fe and S using Ordinary Kriging. Good spatial continuity of the all studied variables, including gold, was confirmed by robust 3D directional variograms. Pyrite ‘pyrite equivalent’ was estimated using the stoichiometric chemical composition of pyrite from the sulphur resource estimation.

The Resource was estimated as blocks of dimension 20 x 20 x 2m. A top-flattening unfolding algorithm was applied in order to accurately represent the layered structure of the tailings.

Estimation was made using a narrow horizontally oriented search ellipse at two passes, 1st pass 50 x 50 x 4m (minimum 6 and maximum 32 samples from 16 sectors) and 2nd pass 80 x 80 x 10m (minimum 4 and maximum 32 samples from 16 sectors). Estimation of silver, copper, iron and sulphur required third pass, 240 x 240 x 30m (minimum 4 and maximum 32 samples from 16 sectors). The third pass was estimated using simple kriging with a global mean.

The estimated Resource is reported at a zero cut-off (0.00 g/t Au) to reflect the planned mining and processing of 100% of the tailings.

Classification into Indicated and Inferred categories is based on geostatistically estimated uncertainty using the Sequential Gaussian Conditional Simulation method of the gold grade.

Full details of the JORC Code 2012 reporting criteria and input parameters used to estimate the Resource are provided in Appendix 1.

Metallurgical recovery of the tailings has been
extensively carried out by Carbine over several
phases from 2014 to 2015. The phase 3 testwork
for the pre-feasibility study provided the
generation of three products from sulphidic tails –
gold bullion, copper sulphate and a premium grade
pyrite concentrate. 76% gold recovery, 90% pyrite
recovery and 68% copper recovery (ASX: 23rd
July, 2015). Red oxide tailings are blended with
testwork suggesting a 74% gold recovery and 51%
copper recovery.

The use of geology in
guiding
and
controlling
Mineral Resource estimation.
Understanding of the tailings deposition procedures has
suggested the following interpretations, which were
incorporated into the estimation procedures:

Two types of the tailings materials, red oxide and
sulphidic tailings are present in the tailings. They have
been offloaded to the tailings dam at different times in
the history of the project. Therefore they are not
intercalated in the tailings, but rather are distributed as
separate domains.

Tailings were infilled evenly creating horizontal layering
to the mineralization. Therefore narrow and horizontally
oriented search ellipses were used in estimating the
block modelgrades

Surface topography was created by wireframing the

Mineralisation was constrained as 3D closed wireframe
(solid). All wireframing was made using Micromine©

Geometry of mineralized tailing was modified by applied
top-flattening unfolding algorithm

Mineralisation grades (Au, Ag, Cu, Fe, S) were estimated
using kriging technique. All geostatistical studies were
made using Isatis©

Sulphur (S, wt%) grade was converted into the ‘pyrite-
equivalent’ (wt%) using stoichiometry of the pyrite,
 formula - FeS2
 chemical composition Fe – 46.6%, S – 53.4%
(this corresponds to 100wt% of pyrite in a
sample)

Validity of this approach is based on a good correlation
between S% and Fe% in the drillhole samples and
estimated block modelgrades

Oxide tailings (Red Oxide) were produced pre-1927 from
processing of oxidized ore from the Mt Morgan deposit.
Between 1932 and 1964 several generations of Mt Morgan
sulphidic tailings were produced and deposited in Mundic
Gully. Reprocessing of the Mundic Gully sulphidic tailings
commenced in 1986 until 1989 where it is estimated that
approximately 2.0Mt was reclaimed. The new resource
figures are in close agreement to that predicted by historical
records.
No production figures for oxide tailings have been located.

The assumptions made
regarding recovery of by-
products.
Three products from sulphide tailings – gold bullion, copper
sulphate and a premium grade pyrite concentrate are
generated. 76% gold recovery, 90% pyrite recovery and 68%
copper recovery (ASX: 23rd July, 2015). Silver is also a
minor byproduct.
Two products from oxide tailings - gold bullion and copper
sulphate

significance (eg sulphur for

drainage
characterisation).
All samples have been assayed for Au, Ag, Cu, Fe and S.
Contents of other potentially deleterious components
(arsenic, antimony) is negligible in the primary Mt Morgan
deposit and were not systematically assayed in this tailings
drilling.
All sulphidic tailings are being mined and processed. A
pyrite concentrate is produced and then taken to the Port of
Gladstone hence removing the current environmental
liability.
In the case of block
model interpolation, the block
size in relation to the average
sample
spacing
and
the
search employed.
Drillholes are distributed approximately as 40 x 40m grid and
they were sampled at 1m intervals.
Blocks (parent cells) are 20 x 20 x 2m, which is sufficient to
obtained accurate estimate using Ordinary Kriging technique
applied to the data distributed as 40 x 40m grid.
Third pass of estimate for Ag, Cu, Fe and S was made using
Simple Kriging (SK) method with a global mean.
Any assumptions behind
modelling of selective mining
units.
It is assumed that tailings will be mined by 4m benches,
which locally can be split into 2m flitches. Thus, the mining
selectivity is likely to be in the range of 10x10x2m to 20 x 20
x 4m. The block model parameters used in the current
estimate are in a good accordance with the envisaged mining
selectivity.
It is also noted that previous estimates made by Coffey in
2008 used similar block model parameters. Their parent
blocks were 25x25x2m.
Any assumptions about
correlation
between
variables.
Sulphur and Iron exhibit strong correlation (rho =0.68).
Copper, Gold and Silver show little correlation with Sulphur

The contacts of the Mundic tailings were determined by
logging the drillhole cuttings. This was checked, and if
necessary corrected after obtaining the assay data as
overburden and basement rocks are commonly lacking in
both sulphur and gold grade.
Resources were reported at a zero gold cut-off grade, because
the production plan requires extraction and processing of all
tailings material for final environmental reclamation.
Reporting at a cut-off grade of 0.50g/t results is only a 0.3%

Mining factors
or
assumptions
(3.8)

Assumptions
made
regarding possible mining
methods, minimum mining
dimensions and internal (or,
if
applicable,
external)
mining dilution. It is always
necessary as part of the
process
of
determining
reasonable
prospects
for
eventual economic extraction
to consider potential mining
methods, but the assumptions
made
regarding
mining
methods
and
parameters
when
estimating
Mineral
Resources may not always be
rigorous. Where this is the
case, this should be reported
with an explanation of the
basis
of
the
mining
assumptions made.
Tailings have been partially mined in the past, therefore their
amenability to open pit mining is well understood and
confirmed by past production.

Metallurgical
factors
or
assumptions
(3.9)

The
basis
for
assumptions or predictions
regarding
metallurgical
amenability. It is always
necessary as part of the
process
of
determining
reasonable
prospects
for
eventual economic extraction
to
consider
potential
metallurgical methods, but
the assumptions regarding
metallurgical
treatment
processes and parameters
made when reporting Mineral
Resources may not always be
rigorous. Where this is the
case, this should be reported
with an explanation of the
basis of the metallurgical
assumptions made.
The project flowsheet incorporates the upfront extraction of
copper via resin-in-leach, followed by pyrite flotation to a
saleable concentrate, and finally gold extraction by carbon-
in-leach.
Metallurgical recovery of the tailings has been extensively
carried out by Carbine over several phases from 2014 to
2015. The phase 3 testwork for the pre-feasibility study
provided the generation of three products – gold bullion,
copper sulphate and a premium grade pyrite concentrate.
76% gold recovery, 90% pyrite recovery and 68% copper
recovery (ASX: 23rd July, 2015).

Environmental
factors
or
assumptions
(3.10)

Assumptions
made
regarding possible waste and
process
residue
disposal
options.
It
is
always
necessary as part of the
process
of
determining
reasonable
prospects
for
eventual economic extraction
to consider the potential
environmental impacts of the
mining
and
processing
operation. While at this stage
the determination of potential
environmental
impacts,
particularly for a greenfields
project, may not always be
well advanced, the status of
early consideration of these
potential
environmental
impacts should be reported.
Where these aspects have not
been considered this should
be
reported
with
an
explanation
of
the
environmental
assumptions
made.
Mining license includes all necessary environmental permits
for mining and processing of the tailings.
A special requirement is the extraction of all tailings
material disturbed to eliminate the acid-waste drainage from
these tailings. This condition has imposed the necessity to
report resources at the zero grade cut-off.
Sulphidic waste overburden is assumed to be encapsulated
in benign reprocessed tailings.
Bulk
density
(3.11)
Whether assumed or
determined. If assumed, the
basis for the assumptions. If
determined, the method used,
whether wet or dry, the
frequency
of
the
measurements, the nature,
size and representativeness of
the samples.
Dry bulk density was measured using the sand replacement
method. The method is certified in Australia (Australian
standards - AS1289.5.3.1) for measuring densities of the soft
materials. It was applied to the tailings which were exposed
in the specially excavated trenches.
In total, 18 measurements have been made, including 14 of
the pyritic tailings and 4 oxide tailings

Mundic (fresh) - 4 measurements

Shepherd’s (fresh) - 6 measurements

No 2 (fresh) - 4 measurements

No 2 (oxide) - 2 measurements

Red Oxide (oxide) - 2 measurements
Based on these study the DBD values used for estimating
resources were as follows:

[email protected] www.carbineresources.com.au

==> picture [40 x 40] intentionally omitted <==


Pyritic tailings – 1.76 t/m3

Oxide tailings – 1.42 t/m3
The bulk density for bulk
material must have been
measured by methods that
adequately account for void
spaces (vugs, porosity, etc),
moisture
and
differences
between rock and alteration
zones within the deposit.
Sand replacement method was applied rigorously following
the procedures described in the Australian standards manual
(AS1289.5.3.1)
Discuss assumptions for
bulk density estimates used in
the evaluation process of the
different materials.
Average density values have been used in the resource
estimation, despite the variations of the measured results. Use
of the average values was necessary because the number of
measurements was insufficient for estimating the local
density.
The current density estimate is likely to be conservative due
to the more pyrite-rich tailings being located in the middle
and lower parts of the tailings and the density of that material
is likely to be higher.

Classification is based on geostatistically estimated
uncertainty of the gold grade. The uncertainty was estimated
using Sequential Gaussian Conditional Simulation method
applied to the Shepherds Gully tailings.
Results shows that using a drilling grid of 40 x 40m will allow
estimation of grade for large blocks (350 x 350 x 5m) with an
error less than +/-15% (at 0.95 confidence limits). The chosen
block size is matching the annual production volumes
proposed for the tailings.

This level of uncertainty, applied to the blocks representing
the annual production from the tailings is in good accordance
with the industry practices for classification endowment as
Indicated Resource.
Limitation of this approach is that it was applied to the
‘Shepherd’s’ tailings dump and these results were
extrapolated to ‘No2 Mill’, ‘Mundic’ and ‘Red Oxide’

Discussion of

(3.14)
Where appropriate a
statement of the relative
accuracy
and
confidence
level in the Mineral Resource
estimate using an approach
or
procedure
deemed
appropriate by the Competent
Person. For example, the
application of statistical or
geostatistical procedures to
quantify the relative accuracy
of the resource within stated
confidence limits, or, if such
an approach is not deemed
appropriate, a qualitative
discussion of the factors that
could
affect
the
relative
accuracy and confidence of
the estimate.
A Conditional Simulation study undertaken in 2015 using the
data from the Shepherd’s tailings has shown that using a
drilling grid of 40 x 40m will allow estimation of grade of the
large blocks (350 x 350 x 5m) with an error less than +/-15%
(at 0.95 confidence limits).
Actual uncertainty of the grade at the Mundic Gully tailings
dump was not tested and it is assumed that results obtained at
the ‘Shepherd’s’ tailings are applicable to other tailings at the
historic Mount Morgan mine site.
A drill density of 40m x 40m is deemed appropriate given the
nature of the tailings mineralisation.
The statement should
specify whether it relates to
global or local estimates,
and, if local, state the relevant
tonnages, which should be
relevant to technical and
economic
evaluation.
Gold grade uncertainty was estimated using Conditional
Simulation (Sequential Gaussian Simulation) method for the
blocks, corresponding to annual (12 months) production
volumes.
